Security issues fixed:
* Fixes CVE-2015-4625, a local privilege escalation due to predictable
 authentication session cookie values. Thanks to Tavis Ormandy, Google
 Project Zero for reporting this issue. For the future, authentication
 agents are encouraged to use PolkitAgentSession instead of using the
 D-Bus agent response API directly. (bsc#935119)
* Fixes CVE-2015-3256, various memory corruption vulnerabilities in use of
 the JavaScript interpreter, possibly leading to local privilege
 escalation. (bsc#943816)
* Fixes CVE-2015-3255, a memory corruption vulnerability in handling
 duplicate action IDs, possibly leading to local privilege escalation.
 Thanks to Laurent Bigonville for reporting this issue. (bsc#939246)
* Fixes CVE-2015-3218, which allowed any local user to crash polkitd.
 Thanks to Tavis Ormandy, Google Project Zero, for reporting this issue.
 (bsc#933922)
Other issues fixed:
* On systemd-213 and later, the 'active' state is shared across all
 sessions of an user, instead of being tracked separately.
* pkexec, when not given a program to execute, runs the users shell by
 default.
* Fixed shutdown problems on powerpc64le (bsc#950114)
* polkit had a memory leak (bsc#912889)");
